ABSTRACT:
A moisture- and heat-resistant flexible polyurethane foam, which is free from lowering of the foam hardness due to moisture absorption during or after the production of the foam under a high temperature and high humidity condition and free from development of scorch during the production of the foam, can be obtained by adding an amino acid or an amino acid analogous compound to a raw material mixture, and foaming the resulting mixture.
